【Abstract】 By calculation and analysis of the rotor temperature field and stress field,results for low cycle fatigue life expenditure of rotor metallic material hardness value are obtained,which is under increasing decline.A reasonable suggestion for generating sets is put forward on the basis of life expenditure situation of No 5 generating set in a power plant since it is put into operation.更多还原
